keys/trusted_keys: fix handle passed to tpm_buf_append_name during unseal
TPM2_Unseal[1] expects the handle of a loaded data object, and not the
handle of the parent key. But the tpm2_unseal_cmd provides the parent
keyhandle instead of blob_handle for the session HMAC calculation. This
causes unseal to fail.
Fix this by passing blob_handle to tpm_buf_append_name().
